This process does not add any significant thermal budget to the wafer front side and therefore allows a “short thin wafer” process, means completing the wafer front side including the imide process before thinning and backside metallization. By that means both the risk of wafer breakage and substrate contribution to the total device resistance are minimized at the same time. This is clearly shown by comparing 650V SiC Schottky diodes with identical device structure but different total chip thickness (360 vs 110 μm). Besides the advantage in differential resistance also other properties like heat flux through the device (Rth), non destructive surge current density (I2t) and reliability are improved by the SiC thin wafer technology enabled by the laser backside contact annealing.","PeriodicalId":175520,"journal":{"name":"2013 25th International Symposium on Power Semiconductor Devices & IC's (ISPSD)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128790393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The capacitors are charged and discharged by a voltage pulse through an external resistor and the voltage and current across the capacitors are measured as a function of time. The stored charge in the nonlinear output capacitor is shown to be related to the voltage across it in a piecewise nonlinear way as v=aq+bq2 for v<;vlp and v=vlp+c (q-qlp) +d (q-qlp) 2 for v>vlp. The voltage, vlp and the charge, qlp and the constants, a, b, c and d are related to the design of the super junction MOSFET drift region. It is shown experimentally that when the output capacitor associated with the super junction MOSFET is excited by a sinusoidal wave, a large number of harmonics of the fundamental frequency is obtained due to its nonlinearity.
